69-kV High-Pressure Oil-Filled Pipe-Type Submarine Lines to Offshore Drilling Islands

A dual 69-kV high-pressure oil-filled pipe-type cable system was recently installed by the Southern California Edison Company, Los Angeles, Calif., to serve four offshore oil drilling islands in Long Beach Harbor. Each line is capable of carrying the entire load with parallel line out of service. A submarine pipeline was severed and repaired. Cable pulls, believed to be the longest on record, are discussed. Cable tests indicate higher permissible pulling tensions.
